Build 8776 first impressions (Shared calendars/meeting rooms not working Outlook MAPI) WORKAROUND FOUND!
Question asked by Brian Bjerring-Jensen - 1/17/2024 at 2:19 AM
Kyle did our upgrade since the last one went horribly wrong and we needed an emergency ticket to get the services back online.

This time everything went smoothly and the first impressions are great.

The webinterface is significantly faster.
Outlook loads faster.
Webmail loads faster.

Diagnostics page has significantly less info. Its by design apparently.
Background Color on the webmail login box has changed from white to grey. I had to change our loginlogo from .jpg to .png to make it look okay again.

I havent really looked into the logs yet to check for errors but right now no complaints from clients.

All shared calendars and Rooms are gone.

Cannot be clicked in Outlook. Back to may 2023.
Had Tony on a remote session and the workaround is having only one MAPI account in Outlook and the rest as IMAP.

The problem will be escalated asap and in the meantime, the above workaround can be used.
This workaround doesn't work for me...
I can't risk having dozens of users who currently have multiple MAPI accounts no longer seeing the other shared calendars and therefore having to call them to reconfigure their Outlooks for this reason...

Unfortunately I will still have to wait for newer releases with additional BUGFIXes to come out before I can abandon stable 8664 and move on...

Hi Gabriele. I fully understand. We were on 8664 as well and running with very few issues.
